The hostess really sets you up for success: sending detailed maps and images to help find the place (which is in a very convenient location), universal powerstrip, electric kettle, lots of soap, some water, and a wonderful air con.
The school nearby does play loud music around 7-8 in the morning, but I was usually awake around sunrise ~5 so that wasn't an issue for my sleep; but it's good to be aware of. All in all I'd say it was a nice place to stay for my week in Bangkok.
